SPECIFICATION forming part of Letters Patent No. 671,968, dated April 1 6, 1901.

' Application filed August 18 1899- Serial No. 727,712. 1% model.)

To all whom it may concern:

Be it known that I, ERNEST R. KITTREDGE, acitizen of the United States, residing atTenafly, county of Bergen, State of New Jersey, have invented certain new and useful, Improvements in -Filing Envelope, fnlly described and represented in the following specification and the accompanying drawings, forming a part of the same.

The object of the present invention is to adapt envelops to be grouped in piles and all of the envelope in the piles clamped together at one edge to secure them in a binder for ready reference. To prevent the con tents of the envelops from being caught along the edge where the envelope are clamped, each envelop is formed with a shank to he clamped together with the adjacent shanks. The insertion of'mat-ter within the envelope tends to thicken the pile of envelope, and to make the shanks of the-envelope of corresponding 7 thickness each'sh-ank is preferably formed in the present invention with a long narrow pocket to receive a filler. Such filler in practice is proportioned inits thickness to compensate for the contents of theattached envelop, and the shanks of all the envelope ,th us presentthe same aggregate thicknessas the filled envelops themselves. As the invention is intended for envelope which are piled together in a series or group, it consists, broadly, of afil-ing-envelophavingashank across one end thickened to compensate for. the inclosed matter. T116 thickened shank in such an envelop performs aTdiiferent function from the thickened end of a tag, which is sometimes provided merelyto strengthen or protect the material, but is not-adapted to compensate for the thickness of the matter inserted in the envelop and does not therefore furnish any means for securing loose papers within that class of binders which is provided with a clamp having attached covers. Such clamps are commonly used with mere leaves of paper termed filing-sheets. It is common to attach invoices and other papers to such filingsheets; but whereone end or shank of the sheet is held in a clamp having attached covers the matter secured upon the filing-sheets forces the covers inconveniently apart.

By employing an envelop for filing loose papers I obviate the necessity of gnmming or securing them upon a filing-sheet and prevent'the crowdingof the covers apart by thickening the shank or end of the envelop which is to be grasped by the clamp. Where the contents of the envelope in a given binder is of uniform thickness, the shank of the envelop can be thickened by an integral pad or the compensation efiected by loose strips insert-ed between the shanks in the binderclamp; but I am able to compensate for the variable thickness of the matter in the envelops by forming a long narrow pocket Within the shank of the envelop, in which'pocket a filler of any thickness may be readily inserted.

This improved envelop-is especially useful with the socalled post-binder, which has a base to which the posts are attached and a clamp secured movably upon the posts .and furnished with a hinged cover, and for such use the thickened shank of the envelop and the fillers employed in the pocket of the envelop (if one be used) are provided with holes to fit upon the binder-posts.

The invention will be understood by refer- 'ence to the annexed drawings, in which-- Figure l is a perspective view of a postbinder-cont-aining a number of my filing-envelops. Fig. 2 is an edge view ofa filing-en.- velop withpocket formed in the shank. Fig. 3 is a plan of the envelop shown in Fig. 2. Fig. 4 shows the blank for the same envelop. Fig. 5 is a longitudinal section of an envelop having a thickening-filler inserted in the bottom. Fig- 6 is a plan of anenvelop with a shank portion partly folded .for thickening the same and dotted lines showing intended folds in such portion. Fig. 7 is a perspective View of the same envelop, the opening being at one edge, which is shown in the topofthe View. Fig. Sshows the blank for the envelop represented in Figs. 6 and 7, and Figs. 9 and 10 are respectively a side view and edge view of a thickener or filler for use with the envelop-shanks.

In Figs. 2, 3, and 4:, A A designate the flat sides forming the body of the envelop, l; the flap to closethe month of the envelop, and (I the tongues for closing the edges of the onvelop. The sides A and A are formed int-cgral, as shown in Fig. 4;, and folded over upon the dotted line a.

i sent a strip of gum, which attaches the sides A and A together at a suitable distance from 5 the line a to form a hollow pocket in the shank D, asshown in Fig. 2. A filler c is shown insertedin the pocket to make the shank of the.

same thickness as the envelop when filled with certain papers, as represented in Fig. 2.

The binder shown in Fig.1 is provided with base E, posts F, clamp G, and cover H. The thickened shanks D when secured in the binder compensate for the matter inserted in the envelops, so that the cover H is not forced I5 inconveniently upward, but lies naturally parallel with the base E, and if all of the envelops filed in the binder are removed at any' time and secured together in a bundle the same effect is produced and the shanks and bodies of the envelops form a package of uniform thickness.

The ends of the pocket in the shank D are not coveredby the tongues C, but remain open for the insertion of a filler, and the latter may be secured therein by gum, if desired, but requires no fastening if the shank he formed with holes f for application to binder-posts, as the posts intersect both the shankand the filler and hold the latter in place. The filler 0 may be inserted in the bottom of the envelop,

as shown in Fig. 5, without securing the sides A and A together by gum at the inner edge of the shank, as shown in Fig. 2, and the section in Fig. 5 serves to show a. filler which may be either inserted in a pocket having open ends or inserted in the bottom of an envelop having no opening besides the mouth to which the flap B is applied.

Fig. 5 shows the hole f'for a binder-post in- 40 tersecting the shank of the envelop and the filler c.

With the'construction shown in Fig. 5 the filler forms a bottom for the envelop at right angles to the sidesA A. Fig. 7 shows in per- 'spective one'edge of an envelop formed from the blank represented in Fig. 8 and having an open mouth upon one side instead ofupon the end opposite the shank. In this construction the side A of the envelop is not'attached to one end of the side A, as in Fig. 4, but upon its opposite edges, leaving the room upon one end of the part A for an extended tongue D to be folded 'over and over for thickening the envelop-shank. Theend of the part A opposite the tongueD is formed with a short flap g to close the outer end of the envelop.

' Where papers are filed by gumming or se- The dotted lines b repre-.

is correspondingly increased if each is fastened separately in the binder or attached to the filing-sheet.- The presentinvention therefore greatly facilitates the filing of loose papers, as the envelop is adapted to receive papers of various sizes and holds themin the most convenient form for inspection, as they can be removed from the envelop for examination without detaching any fastenings upon the binder.

I claimv 1. A filing-envelop having a receptacle closed upon three sides to receive papers, and having a shank at one end beyond the closed side of said receptacle, the saidshank being thickened to correspond with the thickness of the envelop and its contents, and provided with holes arranged to fit the "posts of a post-binder,substantially as herein set forth.

2. A filing-envelop having a receptacle closed upon three sides to receive loose papers, and having an integral portion across one end beyond the closed side of the receptacle folded over and secured to the body to form a shank provided with a long narrow v pocket, and a-filler inserted in such pocket 0 to compensate for the en velops conten ts, su bstantially as herein set forth.

3. A filing-envelop having a receptacle with flap at one end to close the same, and having at the opposite end a long narrow pocket with its openings at opposite edges of the envelop, and a filler inserted int-he pocket to compensate fortheernvelops contents, substantially as set forth. 1

4. A filing-envelop having a receptacle closed uponthreesides, and having at one end a flap to" close the receptacle-and at the other end a'shank beyond the closed side of the receptacle, such shank being thickened to compensate for the envelops contents, I05

and the envelop having a table printed upon the outside of the envelop to receive a list of such contents.

Intestimony whereof I have hereunto set my hand in the presence of two subscribing no Witnesses: JOHN J. MCBRIDE, THOMAS S. CRANE.
